Fig. i4 is a side 'elevatioiigof the bunehiitg device at the conclusion, of thee blinehing- The cigar bunhes 'W are lqcat'ed in H19 roller 5 is mounted in the ends 6 of a double armed rock lever 7 arranged laterally of the table 4 which rock lever swings about an axis 8 on the machine frame. The rock lever 7 is formed with a slot 9 in which engages a roller 10 on a crank pin 10 of a crank disc 11, the driving shaft 12 of which is mounted in the machine frame A. The shaft 12 is driven by means of toothed gearing 13 and 14 from the shaft 15.

The free ends of the levers 7 are fitted in brackets 16 in which is mounted a guide roller 17 for the apron. In the brackets 16 are provided guide slots 18 in which is guided a rod 19 which carries two forming blocks 20 for forming the ends of the bunch. These forming blocks 20 may be adjusted on the rod 19 and secured in position by means of screws 21.

With the rod 19 engage bell crank levers 22 whichare mounted at the outer ends of the rock lever 7 and rock about pivots 23. The free arms of the bell crank levers 22 carry rollers 24 which track cams 25. The cams 25 are pivoted at 26 to the, two longitudinal sides of the table 4 and at 27 are each pivotally connected with a bell crank lever 28 which may rock about pivot 29 on the frame A. The free arms of the bell crank lever 28 engage by means of rollers 30 on the cam grooves 31 of cam discs 32 which are mounted on a common shaft 33. The shaft 33 carries a pinion 34 which meshes with the pinion 14's0 that the cam discs 32 are driven by the shaft 15.

In the inoperative position the rock levers 7 are located at the left hand dead centre (not shown), the apron 1 lying in a recess 35 on the table 4 which is of the form of the cigar bunch. The cigar bunch is laid in this recess and on the lever 7 being swung to the right of Figs. 1 and 2 in consequence of the tension on the apron 1 secured at one end to the end of the table is raised by the roller 5 out of the recess and brought on to the guide track on the table 4. The rollers 24 of the bell crank levers 22 first slide on projections 36 on the cams. 25; these projections 36 are so formed that the bell crank levers 22 are turned so far to the left that the forming members cannot contact with the cigar bunch. g V y In accordance with the'invention the re sult is obtained in a simple manner by in clining the rod 19 with the forming blocks 20 so that the inclined surfaces 37 of the forming blocks 20 do not bear uniformly against the bunch, the more inclined forming member 20 pressing against the bunch more than the other.

To attain this result only the'cam disc 32 needbe so formed that the'one cam 25 is raised at, a suitable point of time and the other lowered so that the one bell crank lever 22 is turned to the left and the other turned to the right.

In Fig. 1, for example, the lever 22 is turned to the right so that the forming members 20 adjacent this lever lies with a large part of its inclined face against the bunch and forms a cigar tip while the other forming member only bears slightly on it and forms the head end (see also Fig. 3). In Figs. 2 and 4 the same lever is shown turned to the left so that the tip is formed at the opposite end.

The rod 19 is continuously under the action of two springs 38 which are secured to the rock levers 7 and pull the rod 19 towards the bunch so that the forming members 20 are immediately brought into operative position as soon as the cams 25 assume a corresponding position.

In Figs. 6, 8 and 9 is shown a second embodiment of the invention in which the rod 19 for the forming members 20 is longitudinally movable but is not inclined. The cams 25 are in this case secured to the machine frame as indicated in Fig. 6. By a simple displacement of the rod 19 in the longitudinal direction either one or the other of the forming members 20 is pressed with its inclined surfaces more than the other against the bunch according to the direction in which the rod 19 is moved. Figs. 8 and 9 show the rod 19 at two successive dead centre positions. The tip is in the one case formed at a and the next time on the next bunch at the opposite end 5. Longitudinal displacement of the rod 19 can be effected in known manner by a crank, cam discor the like.

The cigar bunch IN is located in the usual apron 1 which is secured in known manner to the ends of the table 4 carried by the machine frame. The surface of the table is of arcuate form and forms a guide track for the roller 5 about which the apron 1 is guided. The spindles of the roller 5 are mounted on the ends 6 of a double armed rock lever 7 arranged laterally of the table 4 which rock lever rocks about a spindle 8 mounted in the machine frame. The rock lever 7 is provided with a longitudinalslot 9 in which engages the crank pin 10 of the crank disc 11 so that on rotation of the crank pin .10 in the direction of the arrow shown in Fig. 13, the two arms 7 arranged to the left and right of the table 4 rock to addition the forming; members 20 v are formed as screw threaded nuts. Each nut is mounted on a screw threaded spindle 41 or 41 which is rotatable as a-hollow spindle on the axis 42. The two spindles are pro-;

to the axis of the spindle 42 and which is engaged by the forming members 20iwith their forked ends 46;

The bearing blocks 44, 44 each fit in a recess 47 on the ends of spindle supporting levers 48, 48.'- The bearing blocks '44, 44' are-adapted to turn in bearings 47 about the vertical pins 49, 49 which are thus at right angles to the longitudinal direction of the spindle 42.

The pinions 43, 43

" spindles 41, 41 engage with the racks 50,

7 with each ratchet wheel.

' 5Ov which are arranged laterally of the apron 1 on the curved surface of the table 4. As the curve formed with the xis 8 as centre and as the .arm 7 swinging about the aXis 8 carries spindle supports 48, 48,

the pinions 43, 43 must roll over the racks 50, 50 when the rock arms 7 perform a swinging movement in the bunching operation. .The spindles 41, 41. are thus rotated as a result of which according to the direction of rotation of the rock arms 7 the formingmembers 20 formed "as screw threaded nuts move outwards or lnwards.

On the axis 8 are rotatably secured two.

ratchet wheels 51, one'oneach side of the 7 table 4. Pawls 52 cooperate with the teeth of these ratchet wheels which pawls, are free to rotate on the associated rock arm 7 and are pressed by a spring the return movement of the wheel after it ing operation, swing fromqthe position shown 1n Fig. 13 into the position shown. in Fig. 14 ,On the return -movement of r 1 move forwards with the,- rock arms 7, the

the arms 7 v the ratchet wheels 5 1 are entrained and rotated through one division; y

A controlling disc 54 is rigidly connected vided on; its periphery with two different groups of controlling teeth in suchqmann'er that a projection- 55 of one group alternates with a projection 56 of the other group; The projections 55 areformed as teeth, with a -continuously increasing cam; surface 57 which cam surface in the embodiment il=- lustrated is ofstraight line, form. The projections 56 however are provided with a of the screw threaded i (not shown); against the teeth of the ratchet wheels 51.v In addi- I tion a safety pawl 53 is provided for each ratchet which in known manner prevents This disc is pro' curved part'58 concentric with the axis of rotation 8 which is transformed later into a gradually increasing curve 59 which is profiled in the embodiment shown as a straight; line.

'The two controlling discs 54 whioha're mounted opposite one another on the axis 8 are now displaced relatively to one another in such 1 manner that on the one side there is always a tooth of the "one group and .on the other side disc 54. These double armed levers turnw about the pivot 61' on the rock arms" 7 Springs 62 ensure thatthe ends 60 will remain in engagement withthe cam discs 54.

The operation of the device is as follows:

If the bunch is laid in the apron and the rock arms 7 v are in the position shownin Fig. 13 then the forming members 20 are in the position shown in Fig; 10.

Now the arms shown by the arrows in'Figs. 13 and 14. in this swinging movement the cam discs 54 remain stationary being held by pawls 53. :The ends60 of the levers 48, 48 are- 7 swing in the direction however operatedby the projections. The I end 60 of the double armed lever 48'at one side of the table 4 comes into engagement with the continuously rising curve 57 of the cam 55 producingfa corresponding swinging movement of the double armed lever 48. There is thus imparted to the end of the spindle 42 a separate movement which causes this'end to approach the bearing'o f the roller5. At the same time the end 60 of the double armed lever 48 on the other side of the table 4 comes into contact with the; concentric portion 58 0f the other cam 56. :As a result at the commencement of 42does not approach the bearing of. the roller 5. The end of the spindle associated with the pinion 43 thus'advan'ccs relatively to" the other endof the: spindle with its I pinion, 43 while both ends" simultaneously members 20 to moveoutwards, the forming I roller '39 however of the onespindle nutj 1 I p'ressing'againstthe end of the bunch and thereby initiating th'e formation of the tip of the cigar while the forming roller 39 of the other spindle nut does not exert any particular pressure on the bunchat theother end (see the'position shown in Fig. 11;);' I 7 On further movement of the arms 7 the i the swinging movementof the rock arms 7 "n i the double armed lever 48 does not swin and accordingly the "other end'ofthe spindle Til end 60 of the double armed lever 48 moves over the curve 59 of the corresponding cam 56 whereby the double armed lever 48 is caused to swing so that the spindle end carrying the pinion 43 also approaches the bearing of the roller 5 and on further outward movement of the corresponding forming member the forming roller 39 forms the end of the cigar on the bunch (see the position shown in Fig. 12).

It is to be noted that the racks 50, with the teeth of the pinions 43, 43 provide a sufficient amount of play so that the comparatively small inclination of the spindle 42 does not cause jamming of the teeth.

After the position shown in Figs. 12 and 14 is attained the arms 7 move backwards. The ratchet wheels 51 are turned so that now the toothed groups of the cam discs at the two sides of the device are reversed. Now, when the next succeeding operative movement of arm 7 takes place, a cigar tip will be formed on the bunch being rolled, at the opposite end of said bunch to that formed on the preceding bunch, and similarly a head end would be formed on, the other end of said bunch. Thus at the conclusion of this next succeeding operative movement of arm 7, the representation of Fig. 14; would be reversed, i. e. the head end of the cigar would be at the left and the tip end at the right. A plurality of rolled cigar bunches arranged consecutively as they come off the forming machine would exhibit alternate heads and tips on the right and left respectively.
